How do I convert a PDF document to a preview image in PHP? [closed]

Answer 1

For those who don't have ImageMagick for whatever reason, GD functions will also work, in conjunction with GhostScript. Run the ghostscript command with exec() to convert a PDF to JPG, and manipulate the resulting file with imagecreatefromjpeg().

Run the ghostscript command:

exec('gs -dSAFER -dBATCH -sDEVICE=jpeg -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r300 -sOutputFile=whatever.jpg input.pdf')

To manipulate, create a new placeholder image, $newimage = imagecreatetruecolor(...), and bring in the current image. $image = imagecreatefromjpeg('whatever.jpg'), and then you can use imagecopyresampled() to change the size, or any number of other built-in, non-imagemagick commands

Answer 2

Here is a simple class I've written and used on a couple of projects. It just wraps imagick and handles writing each page out to disk. If anyone is still looking for an easy way to do this, this link might be helpful.

Answer 3

If you're loading the PDF from a blob this is how you get the first page instead of the last page:

$im->readimageblob($blob);
$im->setiteratorindex(0);

Answer 4

I install finished! It's worked!

You may be do base install imagemagick on windows.

In php (local) use call exec(<command line>) ex:

<?php
$pdf = "filename.pdf";
$info = pathinfo($pdf);
$file_name =  basename($pdf,'.'.$info['extension']);
echo $file_name;
$pdf = "filename.pdf[0]";
exec("convert $pdf convert-img/$file_name.jpg");    
?>

Besides, you may be use class imagick in PHP Imagick class

Thanks all helped me!
